如何在修复文件时连续自动运行gulp eslint - 如何设置手表

Question

我正在和gulp一起尝试.我已经设置了这样的任务:

            gulp.task('lint', function () {
                return gulp.src([
            'components/myjs.js'

                                 ])
                    // eslint() attaches the lint output to the eslint property 
                    // of the file object so it can be used by other modules. 
                    .pipe(eslint())
                    // eslint.format() outputs the lint results to the console. 
                    // Alternatively use eslint.formatEach() (see Docs). 
                    .pipe(eslint.format())
                    // To have the process exit with an error code (1) on 
                    // lint error, return the stream and pipe to failOnError last. 
                    .pipe(eslint.failOnError());
            });

当我跑的时候gulp lint 它告诉我很多错误.现在我试图逐一修复它们.但是我必须gulp lint手动重新运行才能给我一个更新的报告.如何设置它以便每次更新时它都会自动重新运行'components/myjs.js'？

只需添加一个监视任务:

gulp.task('watch', function() {
  gulp.watch('components/myjs.js', ['lint']);
});

这样,Gulp将跟踪您的任何变化,'components/myjs.js'并'lint'在任何变更时执行您的任务
